New study reveals cleaner air could help save lives

http://www.foxnews.com/health/2014/07/16/new-study-reveals-cleaner-air-could-help-save-lives/

While some anti-environmentalists claim that clean air standards will cost Americans jobs, a newly published health study shows that clean air standards may have already saved lives.

Published in the June 2014 Journal of Chronic Obstructive Pulmonary Diseases, the study raises the bar for environmental awareness and provides valuable fuel to the cause of clean air. The research team that conducted the study included scientists from Duke University School of Medicine, the Center for Population Health and Aging at Duke University, the Nicholas School of the Environment at Duke and the N.C. Department of Environment and Natural Resources.

In the study, the Duke researchers analyzed deaths in the state of North Carolina due to respiratory disease during a 17-year period between 1993 and 2010, following the implementation of clean air standards. They found a direct correlation between improved air quality in North Carolina since the 1990s and reduced deaths due to pulmonary disease.

Both national and state air quality standards enacted in the early 1990s have helped to provide cleaner air for the most essential of all human physical functions: breathing. The Duke study provides strong evidence that such air quality standards can help save human lives.

One significant factor in North Carolina was the 1992 Southern Appalachian Mountains Initiative, which led to the enactment of the Clean Smokestacks Act to mandate reduced emissions from coal-fired power plants. Some argue that the coal industry is one of the most toxic of all industries in terms of air pollution, and that it can adversely affect water and soil. The coal lobby has steadfastly stonewalled clean air legislation, but this study stands to significantly change the coal argument.

In the study, the Duke team assessed levels of several toxic and potentially lethal pollutants in the atmosphere during the study period, including those known to emit from coal plants.  These pollutants included ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and particulate matters. Data was gathered from monthly data measurements from North Carolina air-monitoring stations.

The group looked at North Carolina residents of all ages, and adjusted their data to exclude smokers (who often die from respiratory disease) and those who were known to have specific lung disorders. They calculated deaths in the state due to emphysema, asthma and pneumonia and found steadily decreasing rates of related deaths as air quality improved.

“While a few studies have analyzed the associations of both air quality and health over a long period, they were typically limited to analyses of a specific air pollutant or a couple of pollutants,” said Dr. Kim Lyerly, who headed up the study team. “In contrast, we leveraged access to multiple disparate databases containing either environmental or health data, and we were able to study longitudinally a number of air contaminants, including both particulate matter and noxious gases over almost two decades.”

According to the study, atmospheric reduction of the pollutants, most notably sulfur dioxide, carbon dioxide, and particulate matter, directly correlated with lower rates of respiratory deaths.

Many opponents of clean air standards have claimed that there is little science to back up demands for cleaner air, but this rigorous study, which assesses several pollutants and a broad population, provides exactly that science. And while it should be obvious that we all require clean air for healthy respiration, atmospheric standards have been tough to implement, due to strong lobbying in Congress.

In the battle to provide a cleaner environment, the recent Duke study is a landmark event, and it may point the way to a healthier future.

室內空氣檢測:方法正確數據才可靠

IAQ Air Cleaner | http://www.kaixian.tv/gd/2014/0721/7384948.html

因房屋裝修設計等引起的室內空氣污染危害人體健康越來越受到社會關注,但目前國內市場上室內空氣質量檢測公司卻良莠不齊。專家稱,要獲得真實可靠的室內空氣檢測結果,不僅要選對機構還要選對檢測方法。

  湖南省質檢院總工程師姚斌介紹,目前檢測室內空氣質量 IAQ的依據主要是《室內空氣質量標准》(G B /T 18883-2002)。譬如,檢測甲醛的常用方法主要為“酚試劑分光光度法、乙酰丙酮分光光度法”2種。這些方法都需要將抽取的空氣樣品帶回實驗室進行化學分析來進行檢驗,而不能在現場得出結論。

  同時,取樣的方法還必須正確:比如,小於50平方米的房間應設1個-3個點;50平方米-100平方米設3個-5個點;100平方米以上至少設5個點。抽樣前一定要關閉門窗12個小時。取樣時,取樣器應該距牆至少0.5米的距離,高度為0.5米-1.5米,最好與人的呼吸高度一致。對取樣溫度也有規定,如冬天的室內溫度不能低於16攝氏度、夏天的室內溫度不能高於28攝氏度。如不符合,則要采取升溫或降溫措施。

  但目前市場上,各類“專業”檢測室內空氣質量的企業機構數量眾多,資質技術亦良莠不齊,利用“信息不對稱”欺詐消費者的現像時有發生。姚斌說,為了保護消費者權益,湖南省在今年下半年整頓檢測市場。整頓室內空氣質量檢測市場,對非法、非標進行室內空氣質量檢測或出具虛假室內空氣質量檢測報告的行為進行嚴厲查處。(禹志明)

Air purifiers are not always effective, and some may be harmful


IAQ http://www.scmp.com/lifestyle/health/article/1531695/air-purifiers-are-not-always-effective-and-some-may-be-harmful

Air purifiers are not always effective, and some may be harmful

Air purifiers are not always as effective as advertised, and those that emit ozone may even be harmful, writes Elizabeth Choi

With Hong Kong recording its smoggiest day of the year two Sundays ago, perhaps you were persuaded to not only stay home but also invest in an indoor air purifier.

As the air quality index climbs, so do sales of air purifiers in China. According to Euromonitor International, air purifier volume sales in China rose 87 per cent from 2012 to 2013.

Nowhere in the world is the number of air pollution-related deaths climbing as quickly as it is in Asia, especially Southeast Asia. A 2012 study by the World Health Organisation found that, globally, seven million deaths were attributable to the combined effects of household and ambient air pollution.

Southeast Asian and Western Pacific regions - of which China is part - bear the brunt of those numbers, with 2.8 and 2.3 million deaths respectively.

In Hong Kong, the Hedley Environmental Index, a real-time health information system developed by the University of Hong Kong's school of public health, shows a city map that is often dotted with red during the day, indicating the WHO level of permissible short-term exposure to fine particulates and other pollutants is more regularly "very bad" than it is green ("acceptable"), or even yellow ("not good").

So can a household air purifier protect your health indoors? It's easy to get your hands on one in Hong Kong - at a wide range of prices.

A new, moderately sized model that can purify up to 48 square metres (or about 515 sq ft) can cost more than HK$4,000, while a used machine can cost as little as HK$290 on classified sites such as AsiaXpat.

There are several factors to consider when buying an air purifier, including the volume or space to be cleaned, external weather and environmental conditions of the home, and what types of allergens or pollutants are being removed.

"There are many types of air purifiers - some of them sterilise air or use ultraviolet or other heating systems to kill germs," says Dr Fanny Ko Wai-san, a specialist in respiratory medicine and president of the Hong Kong Thoracic Society.

While purifiers with special heating systems may be sufficient for killing germs, they may not be adequate in removing fine or respirable particulates that can exacerbate allergies or asthma.

That's not including toxic gases such as nitrogen dioxide, which comes from gas-burning stovetops, or sulphur dioxide, emitted from cars and ships.

Despite becoming increasingly popular, home air purifiers aren't essential for the average household in Hong Kong, Ko says.

"Most people live without one, and without any problem," she says. "It will not lead to a cure for allergies or asthma. Some patients in previous studies show they have the air purifier, but don't show any signs of improvement. You can install one and find it provides no benefits."

A number of variables determine an air purifier's effectiveness.

"Sometimes, indoors can be very moist and, in those situations, an air purifier can be helpful," Ko says. "But if you open the windows, there's almost no point because the pollution comes in. Can it really help or translate into improvement? It's hard to say."

Ko says air purifiers could be considered for places such as hospitals that need to prevent infection, or work settings in industrial areas with extreme levels of particulate matter.

"In general, however, we do not recommend installing air purifiers unless the asthma is difficult to control. In the end, it's a personal preference over a scientific reason," she says.

Their use might be justified for those with acute allergies or asthma. But even in those cases, most specialists prescribe medicine as a treatment.

Studies and tests show mixed results of how well these machines can purify indoor air from toxins, germs and particulate matter.

Indoor air purifiers are advertised as safe household products for health-conscious people, but some purifiers produce ozone. Those that work by charging airborne particles and electrostatically attracting them to metal electrodes emit ozone as a by-product of ionisation.

Emissions may be a few milligrams of ozone an hour, about as much as a dry-process photocopier emits during continuous operation. In a small, poorly ventilated room, this could create an ozone level that exceeds public health standards, according to a study by the University of California, Irvine, published in 2006 in the Journal of the Air & Waste Management Association.

Ozone can damage the lungs, causing chest pain, coughing, shortness of breath and throat irritation. It can exacerbate chronic respiratory conditions such as asthma and compromise the body's ability to fight respiratory infections.

In 2011, the Hong Kong Consumer Council tested 10 air purifiers priced from HK$629 to HK$4,000, and found that they all provided a less usable area of purified air than they claimed. In seven of the larger models, the shortfall ranged from 12 per cent to 67 per cent. In the three small models, the shortfall was up to 90 per cent.

The study also found the four models provided insufficient protection from electrical leakage, while the plastic parts of some models were insufficiently heat and flame retardant.

Ko says many household cleaning supplies, office equipment such as copying machines, pesticides and painting materials can contain and emit harmful volatile organic compounds (VOCs) that can have short- and long-term effects that range from eye, nose or throat irritation to asthma, and may even cause some cancers.

According to the US Environmental Protection Agency, all of these products can release organic compounds while being used, and to some degree, when they are stored.

"Choose furniture that doesn't have VOCs," Ko says. "Those may be the source of emissions in the home, but an air purifier may not be tackling the source. Clean your carpets, too as they can produce allergens and house a lot of dust.

"A dehumidifier is a home essential. It can help with preventing moisture and mould in the home," Ko says.

空調成夏季室內污染重災區 散熱片細菌是馬桶60倍



IAQ : http://www.ldnews.cn/property/jiazhuangzixun/201407/315258.shtml

夏季的高溫使得空調使用變得頻繁,然而消費者所不知的是,往往夏季的室內污染就是由此開始。據最新實驗數據顯示,在空調長期不使用或者不定期清理的情況下,空調散熱片細菌含量是同樣單位面積下馬桶細菌總數的60余倍。有關專家建議,除經常通風外,定期對空調散熱片和濾網進行清洗已是當務之急。

空調散熱片危害大
數據顯示,消費者平均85%以上的時間是在室內度過的,而夏季,在室內學習和工作的時間甚至達到90%以上。然而往往室內的空氣污染情況要更甚室外,其根源就是家用空調。

日前中國環境科學學會室內環境與健康分會聯合上海家化家安品牌進行了室內空氣測試活動,結果顯示,空調散熱片的“毒性”要大於馬桶,如果消費者忽視空調產品的日常清理問題,室內的空氣環境將更加糟糕。

此前,復旦大學做了一場實驗,對使用分體掛壁式空調的30戶居民住宅做了入戶調研,分別在空調散熱片、馬桶內壁和抹布上取樣,並將收集好的樣本放入培養皿中進行細菌培養並計數,檢測室內分體掛壁式空調散熱片、馬桶和抹布的微生物污染狀況。在此次檢測中,空調散熱片的細菌含量每平方釐米最高可達1200cfu,是馬桶細菌總數的60余倍;而空調散熱片的霉菌總數則高達每平方釐米960cfu,是馬桶的近30倍。

易滋生多種細菌
據中國環境科學學會室內環境與健康分會名譽理事長田德祥介紹,空調污染是夏季室內空氣污染的主要因素,而空調散熱片是空調污染的罪魁禍首。原因在於空調散熱片是冷熱空氣交換的必經之地,冷凝水在這裡產生,長期處於潮濕環境,細菌在此大量滋生。

清華大學建築學院教授張寅平表示,現實生活中細菌是普遍存在的,這是不可避免的,細菌往往依附在空氣中的微顆粒物上,隨空調流動而流動。而空調散熱片正處於空氣流動途經,空氣中的細菌容易在此堆積。另外,空調散熱片附近的溫度和濕度相對而言也較為適合細菌生長。

據一項來自新加坡的研究數據表明,有空調的室內空氣細菌濃度高於無空調的房間。復旦大學調查結果也顯示,有近9成的家庭空調散熱片細菌超標,有的家庭甚至超標1000倍。另外,復旦大學的檢測證實,大多數家庭的空調積塵中細菌、霉菌超標,最嚴重的家庭空調細菌數量超過商場中央空調50倍。

用戶需定期殺菌消毒
業內專家建議,空調用戶可以從換氣、源頭等方面來改善室內空氣質量。張寅平表示,使用空調設備的室內環境相對封閉,空調基本在室內循環,這樣容易導致室內空氣微生物積增無法排出。因此當空調連續使用一定時間後,要開窗通風。

另外,定時清洗和消毒也同樣重要,可以從源頭上進行消毒殺菌。參與此前聯合調查的上海家化家安工程師也建議消費者,當家中空調長時間閑置後,開機前最好能夠清洗消毒一下過濾網和散熱片,這樣能夠有效避免各種細菌進入室內。

空調散熱片因為不可拆卸,僅靠濕布擦拭、刷子清潔等手段是沒有用的,而且還容易損壞散熱片,可以用專用的洗滌劑清洗。對於空調消毒劑品牌的選 擇,業內專家建議選用有權威機構認證對人體和機器安全的、殺菌效果顯著、具有衛生部門“消”字證號的產品。條件允許的話,盡量每個月消毒一次過濾網和散熱片。(編輯/鄧仕姣)

消委會:空氣清新機誇大功能



(星島日報報道) http://std.stheadline.com/archive/fullstory.asp?andor=or&year1=2005&month1=4&day1=16&year2=2005&month2=4&day2=16&category=all&id=20050416a10&keyword1=&keyword2=

空氣污染指數屢創新高,故近年不少家庭都會購買空氣清新機。但消委會的測試顯示,所有空氣清新機有誇大其淨化面積之嫌,有型號聲稱可淨化四百多呎家居,但結果僅為三十呎﹔而消委會又對清新機可殺菌、除病毒的功能存疑。

消委會聯同機電工程署,測試市面十款、售價介乎一千至三千元不等的空氣清新機,測試其淨化效能、寧靜程度、方便性及安全程度。結果發現,以五分為滿分,整體表現介乎三分至四分半之間。各型號的淨化效能十分參差,最低評級僅得二分,最高則為四分。

值得注意的是,所有空氣清新機均有誇大其可使用面積之嫌,其中一款聲稱最大的可使用範圍達四百三十方呎,但消委會的測試結果,僅得三十二方呎,連聲稱的十分之一範圍也不及。

不過,消委會宣傳及社區關係小組副主席程伯中亦指出,在計淨化面積時,現時國際上沒有統一的計算標準,因此,生廠商的計算方法和條件或有不同,兩者數字未必可直接比較。

他指出,不少清新機均聲稱可以除菌、除病毒,但他質疑空氣清新機殺菌及消滅病毒的功效。因為根據專家意見,最有效的方法是找出及控制污染源頭,注意家居生及其他預防疾病措施,不宜單靠空氣淨化機來清除空氣雜質。

在安全性方面,十款測試樣本中,僅得三款完全通過最新版本的IEC國際標準,其餘樣本未如理想的地方,包括部分物料的耐熱或防火程度未符合新規定、絕緣距離不足、帶電部分或基本絕緣可被觸及。

程伯中表示,早期國際間有一套較寬鬆的舊標準,但近年則有一套較嚴緊的要求,不少產品仍沿用過往的生產標準,由舊制過渡至新標準有一段過渡期,故有關產品沒有違規。

消委會並指出,聲稱會產生負離子的空氣清新機,表面上不比純粹用隔塵網的樣本優勝,而結果亦顯示,樣本效能受送風量影響,通常送風量愈高,除塵的速度亦愈高。
